Position description

**Category**:

**Contract**:

- Internship

**Job title**:

- Development of a 1-6µm optical collection for cathodoluminescence H/F

**Subject**:

- The development of infrared imaging systems requires the creation of pixel arrays in structures based on small-gap materials (1-10µm) such as CdZnTe or HgCdTe alloys. Cathodoluminescence is a microspectroscopic technique that can be used to detect the local states present in the gap and thus identify the defects present in the materials of these detectors. This characterisation method is now widely used in the UV-visible range.
The internship involves continuing the development of a 1-6µm detection chain for our cathodoluminescence equipment. It consists of an optical microscope embedded in a secondary electron microscope (SEM), and will therefore allow us to meet these new characterization challenges.
This 4 to 6 month duration internship may eventually continue in the form of a PhD contract that will focus more on using the system developed during the internship to characterize structures for small-gap imagers.
